To clarify the flow characteristics around a circular cylinder in the case of changing the shapes of grooves we analyzed the drag coefficient, lift coefficient, turbulent kinetic energy, and vorticity by applying the RNG k - 蔚 turbulent model. The shapes of the grooves were arced, triangulated ...
Dear All, I am attempting to simulate flow of fluid around a cylinder and understand its behavior with varying Re. I have created a flow field using
The effects of cross-buoyancy mixed convection from a square cylinder in the proximity of a plane wall are studied for Reynolds number (Re) = 1100, Richardson number (Ri) = 02, and gap ratio (G) = 0.251 at Prandtl number (Pr) = 0.7. The flow observed is steady for G = 0.25 and ...
Emphasis will be placed on the overall field but also and more particularly on the field very near to the cylinder. An in-depth rheometric study of the gel and a detailed analysis of the boundary conditions and initial flow conditions will be carried out. The drag coefficient will be ...
The distributions of heat transfer coefficient around a circular cylinder with vortex generators are measured in the Re range 13,000-52,000. The results obtained are discussed in connection with characteristics of flow past cylinders. In particular, attention is given to correlations between heat tra...
The breakdown of finite element (FEM) computations for the steady symmetric two-dimensional flow of dilute and ultradilute Oldroyd-B fluids around a cylinder in a channel, at Weissenberg numbers Wi=O(1), is shown to arise due to a coil-stretch transition experienced by polymer molecules in th...

and the voltage induced in the fluid is measured by two electrodes inserted into opposite sides of the tube. The endsof these electrodes are usually flush with the inner surface of the cylinder. The electrodes are constructed from a material that is unaffected by most types of flowing fluid, ...
The stability of the flow around a rotating cylinder in a fluid linearly stratified along the cylinder axis is studied numerically and experimentally for moderate Reynolds numbers. The flow is assumed potential and axisymmetric with an angular velocity profile Ω = 1/r2, whereris the radial coordina...
